To all wlom it may concern.-

Be it known that I, HERMANN FINGER- HUT, a subject of the German Emperor and residing at Breslau, Germany, have invented certain new and useful Improvements in Fly-Catchers, of which the following is a specificatin.

The present invention has reference to improvements in fly catchers, and relates more specifically to fly catching devices of the extensible kind, which for shipping and storing purposes are collapsed and for use must be pullecl out to their full extent, when the operative surface presented is relatively large; and the particular Object of the invention is to provide means whereby the device in collapsed state, when it lies flat and takes up very little room, is so securely sealed that there is no danger of the adhesive mass drying out or exuding, which two causes, as is well known, very soon render nost of the now marketed fly catchers use'- less, or at least greatly reduce their adhesive properties.

In order to make this invention more readily understood, I will now describe it in detail with reference to the accompanying drawing, in which- Figure 1 represents a perspective view of the device ready for use, on a reduced scale; Fig. 2 shows a plan view of the collapsed and folded-up device; Fig. 3 shows a longitudinal section through Fig. 2; Fig. 4 represents the manner of Opening the device.

The device essentially consists of a hollow body a of suitable material, preferably paper impervious to liquids and air, which in the drawing, by way of eXample is given the form of an obelisk, but which may also be in the shape of a bag or sack, a pyramid, or the like. This obelisk with its lower edges is suitably secured to the base plate or support b, for instance by being glued thereto, and can readily be folded flat onto the base plate, which latter is preferably nollowed-out or dished in its middle part so that the hollow member, when collapsed, snugly fits into the hollow. To the upper end of the member a is secured the handle 0, preferably in the shape of a string or wire loop, which facilitates handling the device in Opening it, and also serves to suspend it.

After the adhesive mixture has been applied to the outer faces of the hollow member, the latter is collapsed on the base plate and this plate is then folded back upon itself on a center line parallel to two side edges, the loop end c partly hanging out, as shown in Fig. 2. The base plate may be made in one and the two halves bent on a weakened line, or it may be composed of two members connect-ed along the bending line in suitable manner, for instance by a strip of gummed paper or fabric. The superposed edges of the plate halves are then sealed by being glued together directly or by means of strips of gummed paper or` the like. In order to make this closure still more perfect, the respective plate halves may be so grooved or corrugated, as at e, that the co-nvex or ridged part of the one half takes into the corresponding concave o-r furrowed part of the other half. v Adhesive strips d then airtightly secure the two support halves in the closed position.

In the base plate there is provided an air hole f, through which the air, o-bviously, has access to the interior of the hollow member, but not to the adhesive outer surface thereof, so that drying-out of the sticky medium is effectively prevented as long as the device is collapsed and closed.

For Opening and setting up the fly catcher, the protruding end of the handle 0 is gripped and guided along between the pasted-together edges of the base plate, as shown in Fig. 4, whereby the seal between the two halves is broken. The support plate is then unfolded and the adhesive member a is set-up by pulling on the handle, and at the same time inflating it by blowing into the aperture f.

What I claim is 1. In a fly catcher, in combination, a foldable dished base plate having an air vent, a collapsible member airtightly secured thereto so as to inclose said air vent, adhesive substance on the outer surface of said collapsible member, a fieXible handle at its free end, said adhesive member adapted to snugly fit the dished portions of said base plate halves in collapsed state, and means for sealing the superposed edges of -the folded base plate, substantially as set forth.

2. In a fly catcher, in combination, a foldable base plate comprising two hinged-together members With interfitting corruga- In testimony whereof I afliX my signature tons along the edges, an adhesive member in presence of two Wtnesses. adapted to be inclosed in collapsed State by said' hnged members, a seal between the HERMANN FINGERHUT' folded-together base plate members, and VVitnesses:

means for breaking said seal, substant-ially SIEGFRIED LUSTIG,

as set forth. ERNST KATZ.
